CAR-DUIVIPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 558,200, dated April 14, 1896.

Application filed October 31,1894. Serial No. 527,572. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN MoMYLEE, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Oar-Dumping Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

My invention relates to an improvement in car-dumping machines, the object being to provide improved means more especially for lowering the contents of cars into the hold of a vessel; and it consists in certain novel features of construction andcombinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of the complete apparatus, and Fig. 2 is an enlarged detail of the hopper.

A represents a truck, which travels on a tracklaid along the wharf or other place where the machine is used. On this truck is pivoted the platform 1 on which the car is elevated and by which it is dumped, a hydraulic lift or other device 2 being provided for the purpose of tilting this platform. At the outer end of the platform 1 an abutment 3 is located for the car 4 to rest against, and at this end the engineers cage 5 is stationed. A hopper A is formed at the rear of this abutment, into which the contents of. the car is dumped.

B indicates the chute, which with its connections constitutes in the main the novel features of the present invention. This chute is composed of several telescoping pipes, preferably three, designated by numerals 6, 7, and 8, respectively, the upper section 6 being the smallest and the next one a little larger to slide upon it, and the thirdsnfficiently large to inclose and slide upon the second, so that an unobstructed interior to the descent of coal is always afforded onthe one hand, and no obstruction is presented to the easy collapse or shortening of the chute when occasion may require it.

The upper end of section 6 maybe squared for convenience to conform to the shape of the hopper and is hinged at 9 to the tilting platform, so that the lower side of the chute always forms a continuation of the hopperbottom whatever the position of the chute. From this hinged point 9 the upper section is cut away on an incline, as at 10, in order not to protrude above the hopper-bottom, and also to afford an opening or mouth of larger area for the reception of the contents of the hopper. This end operates inside of the hopper, and in any of its positions never quite leaves the hopper. The dotted and full lines in Fig. 2 indicate approximately the two extremes of the chutethat is to say, the elevated and collapsed position and the lowered and extended position, respectively-showing that in any position the area of the mouth of the chute is substantially defined by the transverse area of the hopper, and that in its working position (shown in full lines) the area of both coincide; and it may be added in this connection that in the more elevated position .of the chute the extreme upper end. of the mouth at point a. is sufficiently high so that no material can pass over it and escape. This is the position when the coal is started, and as it falls first from the lower end of the car when the end-gate is removed it naturally would not slide far and fast enough to rise above point a, as it might have a tendency to do as the dumping continues when the chute shall have been lowered into the hatch.

The chute may be telescoped in any desired manner. The following means has proved most satisfactory: A cable 11 is secured at some point on the outer end of the platform 1, as at 11, one on each side, although only one is shown in the drawings, they both being side elevations. The cable or cables are then passed downward around sheaves 12, in the present instance on the upper end of lower section 8, though not necessarily so. Each is then passed upward and secured to drum 13, around which the cable or cables are wound in order to shorten or collapse the chute. The drum may be controlled by any approved mechanism. I have shown friction-wheels 14 and 15, which obviously might be gear-wheels, the former, 14, a large wheel on the shaft 16,which carries drum '13, and wheel 15 on crank-shaft 17, which is rotated by pitman 18 from the engine-piston 19. When this particular mechanism is embottom of the boat it is not desirable to drop it the full distance directly upon the bottom of the boat. To obviate this a door 20 is hinged to the lower end of the chute. This door is provided with a latch 21, and a cord 22 extends from the latch to the engineers cage or cab, where its manipulation is entirely within the control of the engineer or operator. With this provision the coal orcontents of the car upon being dumped into the chute strikes upon the door 20. The cables are then slackened and the chute allowed to assume the position shown in full lines. The door is then opened and the contents of the chute is dropped a comparatively short distance before it reaches the boat-bottom, and

' as the boat becomes filled the chute may be shortened correspondingly. Provision has also been devised for swinging the chute todistribute the coal discharged over as much of the space provided: as the size of the hatch and a tilting, platform adapted to receive and dump a car, and having a hopper at one end into which the contents of the car is dumped, I of a chute hinged to the platform, the upper ;open end of the chute being approximately 'as wide from top-to bottom as the discharge will admit. This consists, preferably, of two sets of lazy-tongs 0, one on either side, pivotally connected to the outer end of platform 1 at the same point where the chute is hinged and to each of the lower sections at 24 and 25, the object of this construction being to provide means for applying power to the chute whereby to swing the latter without changing the relative positions of the sections thereof and yet admit of the lazy-tongs folding when it is desired to collapse or shorten the chute. The vibrations are controlled by the hydraulic cylinder 26, pitman 27 extending from the piston-rod to the lazy-tongs. By operating this cylinder the chute may be swung to different positions whether it be extended or collapsed, the lazy-tongs being capable of assumport, adapted to receive and tilt a car to dump its contents, of a chute hinged to the support ing a variety of positions, two only of which are represented in the drawings. In these lazy-tongs it will be observed that the links 30 are employed to prevent binding of the two lower sections of the chute, which would take place if they were omitted.

An apparatus thus constructed may be manipulated to discharge the contents of the car at different elevations in the boat and over considerable area, all of which is possible from specification in the presence of two subscribthe telescoping of the sections of the chute and the mechanism for swinging the chute.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention,

, and hence I do not wish to limit myself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with amovable truck, a tilting platform adapted to receive and dump a car and having a hopper at one end into which the contents of the car is dumped, of a chute hinged to the platform and having an inclined upper end adapted to substantially fill the lower end of the hopper and form a continuation thereof, and means for swinging and adjusting said chute, substantially as set forth.

2. The combination withalengthwise-tilting platform pivoted at a point between its ends, and provided with a discharge hopper or spout, of a chute hinged to the tilting platform, means for elevating or adjusting the chute so as to discharge the coal at various parts of the hold of the vessel, a door hinged .to the lower end of the chute, and a cord extending from the door to some convenient point where it may be operated.

3. The combination with a movable truck,

. device extending from the support to one or more sections of the chute, and means for applying force' to'the lazy-tongs device whereby E to move the chute laterally, substantially as set forth.

5. The combination with a suitable supin position. to receive thecontents discharged from the car, this chute composed of telescoping sections, having a door at the lower end ,to stop the dumped material and the chute constructed and adapted to be extended by i the weight of its contents, and means for collapsing the chute, substantially as set forth. In testimony whereof I have signed this ing witnesses.
